Abstract
The utility model discloses a portable cable protective layer protector defect remedying apparatus. The apparatus comprises a phase line connecting clamp, an overvoltage protecting device and a ground wire connecting clamp. The phase line connecting clamp is composed of three electric appliance wiring clamps which are connected with the three phase line ends of the overvoltage protecting device respectively through a lead and used for making the three phase line ends of the overvoltage protecting device respectively connected with a three-phase (phase A, phase B, phase C) cable. The overvoltage protecting device is a three-phase overvoltage protecting unit and has three phase line ends and one ground wire end. The ground wire connecting clamp which is made of one electric appliance wiring clamp is connected with the ground wire end of the overvoltage protecting device. The portable cable protective layer protector defect remedying apparatus with a simple structure is easy to realize. During an installation process, cable circuits are not required to be power off. The installation process is simple. Convenient operations can be achieved by workers.
